Spoke Hole Pull-Through

Tests the strength and integrity of the spoke holes.

A 2mm steel line with a steel head attached is laced through a spoke hole. The end of the line is attached to a tension gauge, then it is pulled until a crack forms in the spoke hole or the line comes free completely.

High numbers in this test mean a more durable and well-built wheel.
* Our spoke holes are reinforced with a pre-molded carbon strip insert to address this issue, and can withstand pull strength far beyond industry standards.
